About
Current recommendations permit the ingestion of all clear fluids (water, apple juice, black coffee..) during labour. However, regarding food during labour, the recommendations vary. British and European guidelines permit the ingestion of low-residue food during labour whilst guidelines from the United States prohibit having any solid food during labour. The reason for this variation in recommendations is the lack of data on gastric emptying during labour with a conservative approach adopted due to the fear of delayed gastric emptying increasing the risk of regurgitation and pulmonary aspiration in the case of general anaesthesia. This study aims, therefore, to evaluate if the gastric emptying of a light meal is slowed down during labour, using a validated, non-invasive ultrasound method, in four groups of women : Women in labour with epidural analgesia (Analgesia group), women in labor without any epidural analgesia (Parturient group), women in the third trimester of pregnancy (Pregnant group) and women who are not currently pregnant (Non-pregnant control group). The investigator propose the hypothesis that the gastric emptying of a light, solid meal is slowed by 30% during labour under epidural analgesia.
